The various features ofrnoveltygwhereby my invention is characterized will hereinafterybet pointed out with particularity in theclaims; but, for a full understanding of my invention Yand of its objects and advantages, reference may be had to the following detailed description taken in .connection with the accompanying drawing, wherein: I

Figure 1 is a central longitudinal section through a dispensing device constructed in accordance with thepresent invention, the intermediate part between the twoends being broken y away; Fig. 2 is a top plan view of the device, Vshowing only the upper end; and Figs. 3, il, 5, 6 and '7 are sections taken, respectively, ori-lines 3 3, 4 4, 5-5,66 andi-1 of Fig. 1.

VReferring to the drawing, I 'represents A,a

tioned that normally the springs I4, acting through the air pipes I I, draw the valve 2l down against its seat, thereby sealing the chamber I against escape of air into or the entry of liquid from the bottle or other container. However, when the cap l5 is pushed up as, vfor example, by pressing a tumbler B or other receptacle against the under side of the arms I6, the valve 2I is raised from its seat and air can escape from the chamberinto the container whenever it must do so in order to replace liquid that is being discharged.

Means are provided to operate the liquid con-l trol valve 1 simultaneously with the air yvalve 2l. In the arrangement shown, the block 9 has in the sides thereof diametrically opposed longitudinal slots or grooves 24 whose upper ends merge into the ends of the slot I9. Straddling the unmutilated portion of the block bounded by the bottoms of the three slots, is an inverted U-shaped yoke 25 to'which the air valve is attached and which `is slidable up and down on the block. This attachment may be effected by simply extending the valve stem through the valve proper as indicated at 26 and through the cross-piece of the yoke, and applying a nut 21 to the free end ofthe part 26. Between the free ends of thel arm of the yoke there is disposed the upper end of a short link or bar 28, secured to these arms by a hinge pin 2S that permits relative swinging movements.

direction except up and down, the part 26 has an additional capacity yfor swinging movements. Screwed into the lower end of the part 28,y for purposes of lengthwise adjustment, the stem of a socket member 30. This socket member has an internal annular groove 3I into which lead two short longitudinal grooves 32 starting at the mouth of the socket. is the upper end of "a rod 34 `provided with a pin 35 extending transversely through the same and projecting a short distance therefrom at each end. Inl order to assemble the rod in the socket, it is aligned with the latter and turned about its axis until the ends of the pin 35 registervwith the two grooves 32. The rod is then pushed vinto the upon` the lower end ofthe rod 34. The stem is provided with a head 38 within the cup,thereby Within the cup is a compression spring 39, resting on the head k38 and bearing against the lower end of the rod 34.

It will be seen that normally both valves are held closed by the springs I4 which are more powerful than spring 39, so that the latter spring will be compressed-to a degree. necessaryfto' allow the. air valve 2I to seat, after the valve 1 is seated. By this means .the complete closing of both valves is assured. Therefore, when the device is attachedfto a bottle, for example, no liquidcan es'- cape from or air enter the bottle even when 'the bottle is turned upside down, as shown. In order vto draw liquid fromrthe bottle, a receptacle, such asindicated at B, is simply positioned under the inverted-bottle andY pushed up:l against the. arms Thus. `whilethe yoke is prevented from moving in anyr I6. This causes the air pipes to move up, raising the air valve and, through the latter, the valve 1. As liquid flows out of the spout, air to replace the liquid, flows from the air chamber in the block 9 past the air valve into the bottle to displace the liquid flowing out of the bottle. It will be 'seen that the air pipes II support the cap I5, withits receptacle-engaging arms by means of which the pipes are raised; open the air valve 2l when the pipes are moved up; permit air from the surroundingA atmosphere to ow up through the same, when up, into the air chamber in block 9; and, because the main valve 1 is suspended from theair valve, cause the main valve to open and ,closel in proper time relation to the opening and closing of the air valve. When the receptacle B is lowered, thevalve 1 closes promptly and since its seatis at the very end of the spout the iiow of Extending into the socket liquid instantly ceases, no liquid remaining in the spout below the valve to produce dripping. Also, because the air valve does not close before-the main valve, no objectionable vacuum is created within the bottle to delay the start of liquid ow "when the next dispensing operation occurs. r

' It will also be seen that the liquid does not come in contact with any metallic part the corrosion of which would result in contamination of theliquid as well as affecting the efciency of the dispensing device; the yoke 25, .link 28', socket member 30 androd 34 being composed ofV glassr or plastic material as'are the cap I5, block 9 andtubes I 3. Since its exposed surfaces are of glass or the like, the device is easily cleaned. .p

Should it be desired to remove the mainvalv for any reason, this can be done quickly, easily and safely. The rod 34 need be given only a half turn and Ythen be withdrawn from the'socket 28 whileV the valves are up in order to detach the rod and permit it and the main valve to v.be

.lifted out Aof the device.
